Why My Ecodial L is showing the following message while doing the minimum conductor sizing for the multi core cable.

FA135918

30 September 2021

 
***> Cable <***

For aluminium, the minimum CSA allowed is 2.5 mm²; Ecodial has calculated a much lower required CSA. In order not to oversize the cable, switch to copper
 
Situation:
As per the given inputs, Ecodial was in a situation to select a conductor size less than 2.5 mm². But it has selected a 2.5 mm² as
a conductor size and it has shown the alarm message as given above.
 
Cause:
As per the standard IEC 60364-5-52 and $ 524.1 the cross-sectional area of line conductors in A.C. circuits and of live conductors
in D.C. circuits shall be not less than the values given in table 52-5.

 
NOTE this is for mechanical reasons.
